Let's divide 61779869 by 721
The aim is to understand the frequency of 721 in 61779869.

Advancing to step 1:
If we divide 6 by 721, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 721

Let's proceed to step 2:
When dividing 61 by 721, we get 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Take the next digit (7) from the dividend and append it to 61, then repeat: 617 / 721

Step 3:
When dividing 617 by 721, we get 0 with a remainder of 617.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 617 and we're left with 617.
Bring next digit (7) of the dividend behind the 617 and repeat the process: 6177 / 721

Moving on to step 4:
If we divide 6177 by 721, we get 8 and a remainder of 409.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 409 after subtracting 5768 from 6177.
Append the next digit (9) from the dividend to 409 and continue with: 4099 / 721

Let's proceed to step 5:
If we divide 4099 by 721, we get 5 and a remainder of 494.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 3605 from 4099, we get 494.
Grab the next digit (8) from the dividend, add it to 494, then carry on: 4948 / 721

Going ahead to step 6:
4948 divided by 721 is 6 with a remainder of 622.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
If we take 4326 away from 4948, we end up with 622.
Include the next digit (6) from the dividend after 622, then repeat: 6226 / 721

Step 7:
The number 721 fits into 6226 8 times, leaving a remainder of 458.
The number 8 becomes the next digit in our result. 
Result so far: 8568.0
Subtract 5768 from 6226 to get 458.
Include the next digit (9) from the dividend after 458, then repeat: 4589 / 721

Let's proceed to step 8:
721 goes into 4589 6 times with a remainder of 263.
Use 6 as the next digit of our solution. 
Result so far: 85686.0
Subtract 4326 from 4589 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 9:
The number 721 fits into 2630 3 times, leaving a remainder of 467.
Write down 3 as next digit of the result. 
Result so far: 85686.3
If we subtract 2163 from 2630, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Let's proceed to step 10:
721 can be fit into 4670 6 times, resulting in a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 85686.36
If we subtract 4326 from 4670, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 11:
721 goes into 3440 4 times with a remainder of 556.
The number 4 becomes the next digit in our result. 
Result so far: 85686.364
If we take 2884 away from 3440, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 12:
5560 divided by 721 is 7 with a remainder of 513.
The next digit of our result is 7. 
Result so far: 85686.3647
Deduct 5047 from 5560 and we're left with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 13:
If we divide 5130 by 721, we get 7 and a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 85686.36477
If we subtract 5047 from 5130, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The quotient of the division is 85686.36477, and the remainder is 8.3e-05.
